CS44800

The Channel Delay bits allow delay adjustment of each of the PWMOUT differential signal pairs, PW-

MOUTAx+/PWMOUTAx- from the associated PWMOUTBx+/PWMOUTBx-. The value of this register de-

termines the amount of delay inserted in the output path. The effective delay is calculated by multiplying

the register value by the period of the PWM_MCLK. This parameter can only be changed when all mod-

ulators and associated logic are in the power-down state by setting the PDN bit in the register “Clock Con-

figuration and Power Control (address 02h)” on page 51 to a 1b. Attempts to write this register while the

PDN is not set will be ignored.
